If I log into labs.azure.com and navigate to one of my labs, I can go into the virtual machine pool page and select one or more virtual machines in the pool. When I make the selection, I get two actions I can perform: "Start" and "Reset". What I would like to know is what happens when I click the Reset button? Does the machine's IP address change? Does the port number on the machines RDP address change? Or does the image just get reset to the template image from which the machine was built?
